Research on the Lowest Navigable Water Lever of Downstream of the Hydro-Junction

Taking the third and the fourth shiplock of the Changzhou Hydro-junction as an example, it analyses the variation of downstream water level and its influenced factors. It adopts a plane 2D mathematical model for total sand to simulate riverbed deformation and transferring law about water level drop from Jieshou to upstream. It estimates water level drop which caused by riverbed scouring and channel regulation engineering in the downstream of the Changzhou Hydro-junction. The lowest navigable water level is obtained. It could provide some technical support for design and new idea for studying similar problems.
